Crack Opening Displacement (COD) concept, an engineering criterion for the initiation of brittle fracture in low carbon steel, has proved itself so effective that proposals have been made on a standard test procedure for determining the critical COD delta sub c as a fracture toughness value, and on the basis of the aforementioned concept defect evaluation standards have been established. However, several matters have to be settled. That the relation between the applied stress and COD can be evaluated correctly only in an ideal state is among them. For this reason, difficulties are often encountered when an assessment of degree of safety against brittle fracture of structural members is attempted on the basis of the COD concept. In this paper, the author proposes a simplified method for evaluating the relationship between applied stress and COD under a unified process as a breakthrough for this problem. By the use of the proposed method, estimation of COD under complex conditions, analytical approach to which has been unavailable so far, and in reverse, evaluation of fracture strength from delta sub c value are attempted whereby the adequacy of the proposed method is discussed. Additional discussions are made on the relationship between the COD obtained by the proposed method and the overall strain.
裂纹张开位移(Crack Opening Displacement, COD)概念作为低碳钢脆性断裂起裂的工程准则，已被证明是非常有效的，因此提出了一种确定临界COD δ sub c作为断裂韧性值的标准试验程序，并在此基础上建立了缺陷评价标准。然而，有几个问题必须解决。其中，只有在理想状态下，才能正确评价外加应力与COD之间的关系。因此，在基于COD概念对结构构件的脆性断裂安全程度进行评估时，往往遇到困难。本文提出了一种统一工艺条件下的应力与COD关系的简化评价方法，作为解决这一问题的突破口。通过使用所提出的方法，在复杂条件下的COD估计，迄今为止还无法获得的分析方法，以及反过来，从δ sub - c值评估断裂强度，并讨论了所提出方法的充分性。进一步讨论了该方法得到的COD与总应变之间的关系。

With the advent of the era of 200-mile economic sea zones, the efficient utilization of coastal waters has increasingly been required. Accordingly, many various facilities for cultivating marine products as well as port and harbor facilities, which used to be installed usually in the shallow waters of a bay, are obliged to be hereafter installed facing the open sea exposed to severe natural conditions. Under these circumstances, the development of the wave reducing device to protect those facilities from high waves surging from the offing has come to be a pressing necessity. To meet the above requirements, IHI has recently developed the floating breakwater through various tank tests and bench tests of mooring parts. The designing techniques of these facilities have been developed based on accumulated field data, laboratory test data and theoretical analysis. Several sea trials were conducted on the full-scale floating breakwater; as a result, the IHI floating breakwater proved to have excellent high wave reducing efficiency and high reliability. The first L type IHI foating breakwater was delivered to Saga Prefecture in November 1977 and is now in successful operation. This paper presents an outline of the development process, test results and design technique of the IHI floating breakwater.
